Ohio Attorney General Mike DeWine says a group wanting to legalize medical marijuana has enough petition signatures, but failed to properly summarize ballot language in its initial effort toward putting the idea before voters.

DeWine has rejected the 2012 ballot proposal by the Ohio Coalition for Medical Compassion. The constitutional amendment would require a prescription for marijuana purchases and allow those qualified to grow a limited number of plants.

An initial 1,000 signatures and approval of issue wording are required before the group can circulate additional petitions. It would then need about 385,000 valid signatures to make the ballot.

DeWine in August rejected another group’s initial effort to get a medical marijuana issue on the ballot because it did not have the required signatures.
